Description

Die Erfindung betrifft eine elektronisch geregelte Fahrzeugbremsanlage.The The invention relates to an electronically controlled vehicle brake system.

Meist finden exzentergetriebene Radialkolbenpumpen Verwendung. Die genannten Hydraulikaggregate sind millionenfach im Einsatz.Most of time find eccentric driven radial piston pumps use. The mentioned Hydraulic power units are in use millions of times.

Jede Kolbenverschiebung während einer Exzenterumdrehung kann stark vereinfacht in einen Saughub (0 – π) und in einen Druckhub (π – 2π) eingeteilt werden. Weil jeweils Flüssigkeitssäulen beschleunigt aber auch verzögert werden, führt dies auf der Saugseite, wie auch auf der Druckseite zu weitgehend sinusartigen Momentandruckverläufen, die in Abhängigkeit von der konkreten Ausführung in Details abgeändert oder auch überlagert sein können. Um unerwünschte Wirkungen der prinzipbedingt schwankenden Momentandruckverläufe zu kompensieren, wird eine Pulsationsdämpfungseinheit vorgesehen.each Piston displacement during an eccentric rotation can greatly simplified into a suction stroke (0 - π) and divided into a pressure stroke (π - 2π) become. Because each liquid column accelerates but also be delayed, this leads to the Suction side, as well as on the pressure side to largely sinusoidal Momentary pressure gradients, which depend on the concrete execution changed in details or superimposed. To unwanted Effects of the inherently fluctuating momentary pressure curves to compensate, a pulsation damping unit is provided.

Beispielsweise ist es aus der DE 34 14 558 bekannt, einen Membrandämpfer mit einer Metallmembran zur Pulsationsdämpfung heranzuziehen. Herkömmliche Membrandämpfer mit einer eingespannten Elastomermembran können unter dem Nachteil leiden, dass diese verschleißbehaftet sind, so dass deren Wirkung mit steigender Lebensdauer abnimmt. Die Federeigenschaften sind davon abhängig, wie schnell die Beanspruchung erfolgt (dynamische Verhärtung).For example, it is from the DE 34 14 558 known to use a diaphragm damper with a metal diaphragm for pulsation damping. Conventional diaphragm dampers with a clamped elastomeric membrane can suffer from the disadvantage that they are subject to wear, so that their effect decreases with increasing life. The spring properties depend on how fast the load is applied (dynamic hardening).

Aus der DE 10 2005 028 562 A1 ist ein Brems-Hydraulikaggregat umfassend einen hermetisch geschlossenen Metallhohlkörper zu Dämpfungszwecken bekannt geworden.From the DE 10 2005 028 562 A1 is a brake hydraulic power unit comprising a hermetically sealed hollow metal body for damping purposes has become known.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine sowohl beanspruchungsgerecht dimensionierte, als auch einfach herstellbare Pulsationsdämpfungsvorrichtung bereit zu stellen.The Object of the present invention is a claim both dimensioned, as well as easy to manufacture Pulsationsdämpfungsvorrichtung to provide.

Die Aufgabe wird mit den Merkmalen vom Anspruch 1 gelöst.The The problem is solved with the features of claim 1.

Weiterbildungen der Erfindung gehen aus Unteransprüchen zusammen mit der nachstehenden Beschreibung anhand der Zeichnung hervor.further developments The invention will become dependent claims together with the the following description with reference to the drawing.

Die einzige Figur verdeutlicht relativ schematischvereinfacht einen herausgetrennten Teilabschnitt vom Hydraulikkreis einer elektronisch geregelten Fahrzeugbremsanlage 1 mit einem Hydraulikaggregat 2 umfassend einen Aufnahmekörper 3 mit elektrohydraulischen Ventilen, mit wenigstens einer hydraulischen Pumpe 4, umfassend einen Saugpfad S und einen Druckpfad D zur Verbindung der Pumpe 4 mit wenigstens einem stromabwärts gelegenen, hydraulischen Verbraucher, wobei zwischen einem Druckmittelvolumen (THZ/Behälter, Niederdruckspeicher) und dem Saugpfad S der Pumpe 4 oder – wie in der Figur verdeutlicht- zwischen dem Druckpfad D der Pumpe 4 und dem hydraulischen Verbraucher, der bevorzugt als Radbremse oder Hauptbremszylinder ausgelegt ist – in einer Aufnahmebohrung 5 eine Pulsationsdämpfungseinheit 6, umfassend einen Metallwellenbalg als bewegliches Trennelement mit definierter Federrate zur Trennung von zwei Kammern 8, 9 von variablem Volumen, vorgesehen.The single figure illustrates relatively schematically simplified a cut-out section of the hydraulic circuit of an electronically controlled vehicle brake system 1 with a hydraulic power unit 2 comprising a receiving body 3 with electro-hydraulic valves, with at least one hydraulic pump 4 comprising a suction path S and a pressure path D for connecting the pump 4 with at least one downstream hydraulic consumer, wherein between a pressure medium volume (THZ / container, low-pressure accumulator) and the suction path S of the pump 4 or - as illustrated in the figure - between the pressure path D of the pump 4 and the hydraulic consumer, which is preferably designed as a wheel brake or master cylinder - in a receiving bore 5 a pulsation damping unit 6 comprising a metal shaft bellows as a movable separating element with a defined spring rate for the separation of two chambers 8th . 9 of variable volume, provided.

Nach der Figur verfügt die Aufnahmebohrung 5 über einen Druckmitteleingang E und einen Druckmittelausgang A, wobei stromabwärts, im Anschluss an den Druckmittelausgang A, bevorzugt eine gesonderte Dämpfungsvorrichtung 10 enthaltend eine Dämpferkammer und/oder eine Blende geschaltet ist. Die stromabwärtigen Verbraucher werden je nach Funktionsfall (fahrerinitiierte oder fahrerunabhängige Bremsenbetätigung) geschaltet.After the figure has the receiving bore 5 via a pressure medium input E and a pressure medium output A, wherein downstream, downstream of the pressure medium output A, preferably a separate damping device 10 containing a damper chamber and / or a diaphragm is connected. The downstream consumers are switched depending on the functional case (driver-initiated or driver-independent brake application).

Im Anschluss an den prinzipiellen Systemzusammenhang wird der Aufbau der Metallwellenbalgdämpfungsvorrichtung wie folgt im Einzelnen beschrieben. Die Metallwellenbalgdämpfungsvorrichtung ist rechtwinklig zu einer Oberfläche 11 im Wesentlichen vollständig in der abgestuft ausgebildeten Aufnahmebohrung 5 von dem Aufnahmekörper 3 derart integriert vorgesehen, dass ein, an einem Bohrungsverschluss 12 mit sämtlichen zugehörigen Bauteilen vormontierter, Dämpfungsmechanismus in die Aufnahmebohrung 5 einsteckbar ist. Folglich wird ein äußert geringer Bauaufwand für die Integration der Metallwellenbalgdämpfungsvorrichtung erzielt. Durch diese Bauform wird insbesondere ein modulares Baukastenkonzept für die Hydraulikanlage ermöglicht, welche es mit einfachen Mitteln erlaubt, mehrere Ausführungsformen mit unterschiedlichen Bohrungsverschlüssen zu kreieren, die wahlweise den Metallbalgdämpfer aufweisen können, oder nicht.Following the basic system context, the structure of the metal wave bellows damping device will be described in detail as follows. The metal wave bellows damping device is perpendicular to a surface 11 essentially completely in the stepped receiving bore 5 from the receiving body 3 provided integrated such that a, on a bore closure 12 with all associated components pre-assembled, damping mechanism in the receiving bore 5 is pluggable. Consequently, an extremely low construction cost for the integration of the metal-wave bellows damping device is achieved. This design allows in particular a modular construction concept for the hydraulic system, which allows by simple means to create several embodiments with different hole closures, which may or may not have the metal bellows optional.

Die Kammer 8 wird von der Aufnahmebohrung 5, vom Metallwellenbalg 7, von einem Bohrungsverschluss 12 sowie von weiteren nicht weiter beschriebenen Kanälen und Komponenten begrenzt, und ist von dem Druckmittel der Fahrzeugbremsanlage beaufschlagt.The chamber 8th is from the receiving hole 5 , from the metal wave bellows 7 , from a bore lock 12 and limited by further not further described channels and components, and is acted upon by the pressure medium of the vehicle brake system.

Die Kammer 9, welche vom Druckmittel der Fahrzeugbremsanlage und auch von der Umgebungsatmosphäre separiert ist, verfügt über eine elastische Füllung. Die Füllung füllt die zweite Kammer im Wesentlichen vollständig aus und kann einen elastischen Füllkörper wie beispielsweise einen Elastomerkörper umfassen. Es ist alternativ oder ergänzend möglicht, dass die Füllung ein Fluid oder ein Gel umfasst. Weiterhin ergänzend oder alternativ ist es denkbar, dass die Füllung zumindest einen Anteil an Druckmittel oder ein gekammertes, konditioniertes (Druck, Volumen, Partialdruck) Luft- oder Gaspolster aufweist. Zur Verdeutlichung unterschiedlicher Werkstoffe ist die Füllung in der Figur mit unterschiedlicher Schraffur versehen.The chamber 9 , which is separated from the pressure medium of the vehicle brake system and also from the ambient atmosphere, has an elastic filling. The filling substantially completely fills the second chamber and may comprise an elastic packing such as an elastomeric body. It is alternatively or additionally possible for the filling to comprise a fluid or a gel. Furthermore, in addition or alternatively, it is conceivable that the filling at least a proportion of Pressure medium or a chambered, conditioned (pressure, volume, partial pressure) air or gas cushion has. To illustrate different materials, the filling in the figure is provided with different hatching.

Für die Ausbildung der selbständig handhabbaren Baueinheit ist der Metallwellenbalg mit einem Fußabschnitt 13 und mit Hilfe einer umlaufenden Schweißnaht 14 hermetisch dicht an einem Zentrierabschnitt 15 vom Bohrungsverschluß 12 angeordnet. Zu diesem Zweck ist der Fußabschnitt 13 von Radial außen auf den Zentrierabschnitt 15 aufgeschoben. Anschließend an den Fußabschnitt 13 verfügt der Metallwellenbalg 7 über seine wellenförmige Wandung 16.For the formation of the independently manageable unit is the metal shaft bellows with a foot section 13 and with the help of a circumferential weld 14 hermetically sealed to a centering section 15 from the hole lock 12 arranged. For this purpose, the foot section 13 from radially outside to the centering section 15 postponed. After the foot section 13 has the metal wave bellows 7 over its wavy wall 16 ,

Gegenüber dem Fußabschnitt 13 wird die Wandung 16 von einem Boden 17 abgeschlossen. Dieser Boden 17 ist einstückig an die wellenförmige Wandung 16 angeformt. Alternativ ist es gemäß der dargestellten Ausführungsform denkbar, den Boden 17 als kompaktes Metallteil vorzusehen, und von innen in einen zylindrischen Endabschnitt 18 der weitestgehend wellenförmigen Wandung 16 einzuschieben. Die Befestigung des Bodens 17 erfolgt anhand von einer umlaufenden, radial außen am Umfang verlaufenden Schweißnaht 19. Ganz generell kann es zur Befestigung des Metallwellbalgs 7 und zur Befestigung des Bodens 17 sinnvoll sein, die Schweißnähte 14, 19 in einen Bereich einer Trennfuge zwischen den jeweils benachbarten Beuteilen zu platzieren, damit die Dichtigkeit auch optisch beurteilt werden kann.Opposite the foot section 13 becomes the wall 16 from a floor 17 completed. This floor 17 is integral to the wavy wall 16 formed. Alternatively, it is conceivable according to the illustrated embodiment, the ground 17 provide as a compact metal part, and from the inside into a cylindrical end portion 18 the largely wavy wall 16 insert. The attachment of the soil 17 takes place on the basis of a circumferential, radially outwardly extending on the weld 19 , In general, it can be used to attach the metal bellows 7 and for fixing the soil 17 make sense, the welds 14 . 19 to place in a region of a parting line between the respective adjacent bundles, so that the tightness can also be assessed visually.

Wie der Figur weiterhin zu entnehmen ist, verfügt der Bohrungsverschluss 12 über eine verschließbare Durchgangsbohrung 20 zum Einbringen der Füllung, so dass die Kammer 9 von Metallwellenbalg 7, Bohrungsverschluß 12 und Verschluss 21 begrenzt ist. Bei dem Verschluss 21 kann es sich mit Vorteil um eine, in die Durchgangsbohrung gepresste, Kugel handeln.As the figure can be seen further, has the bore closure 12 via a closable through-hole 20 for introducing the filling, leaving the chamber 9 of metal wave bellows 7 , Bore lock 12 and closure 21 is limited. At the closure 21 it may be advantageous to a, pressed into the through hole, ball.

Der Bohrungsverschluss 12 als solcher ist druckdicht mit dem Aufnahmekörper 3 verbunden. Dies erfolgt bevorzugt mittels verstemmen, verpressen oder clinchen.The bore closure 12 as such is pressure-tight with the receiving body 3 connected. This is preferably done by caulking, pressing or clinching.
